Fix session outcome showing latest vaccination across all sessions

  PatientSession.vaccinationOutcomes filtered only by programme_id, so
  lastVaccinationOutcome returned the patient's most recent vaccination
  across every session in the programme. Every session row on the patient
  programme page then reported that same outcome.

  Filter by patientSession_uuid too, so each session reports what actually
  happened at that session.

  Surfaced by the seeded Bilal Begum MMR case, where four 'not given'
  sessions between two valid doses were all displaying as 'Vaccinated'.
